Title: TA-55 Hot CMM Calibration Tolerance Analysis (U)

Technical Report ·
DOI:https://doi.org/10.2172/1043515· OSTI ID:1043515

The Hot Coordinate Measuring Machine (CMM), a Brown and Sharpe Xcel 765, has specifications listed by the manufacture of 4.5 + L/250 {micro}m for volumetric performance, 3.5 {micro}m for probing and 4.5 {micro}m for scanning. An upgrade was performed on the machine increasing its performance capability. This document reviews calibration data gathered after the upgrade over a five year period (2005-2010) and recommends a new specification of 3.0 + L/250 {micro}m for size, 3.3 {micro}m for probing, and 4.3 {micro}m for scanning. The new equations are an approximate 30% increase in accuracy for size and approximately 5% increase for probing and scanning.
